Measurement Modes ​

The SDK supports two measurements modes - face measurements and finger measurements.

Face Measurement ​

A face measurement is performed by facing the front (selfie) camera.

Swift
do {
    let licenseDetails = LicenseDetails(licenseKey: "<ENTER_YOUR_LICENSE_KEY>")
    let session = try FaceSessionBuilder()
        .withImageListener(self)
        .withVitalSignsListener(self)
        .withSessionInfoListener(self)
        .build(licenseDetails: licenseDetails)
}
catch {
    let e = error as NSError
    print("Received Error. Domain: \(e.domain) Code: \(e.code)")
}
Objective-c
BNHLicenseDetails *licenseDetails = [[BNHLicenseDetails alloc] initWithLicenseKey:@"<ENTER_YOUR_LICENSE_KEY>"];
BNHFaceSessionBuilder *sessionBuilder = [[[[[BNHFaceSessionBuilder alloc] init]
                                           withImageListener:self]
                                          withVitalSignsListener:self]
                                         withSessionInfoListener:self];


NSError *error = nil;
id<BNHSession> _Nullable session = [sessionBuilder buildWithLicenseDetails:licenseDetails
                                                                     error:&error];
if (error != nil) {
    NSLog(@"Received Error. Domain: %@ Code: %ld", error.domain, (long)error.code);
}

Finger Measurement ​

Deprecation Warning

Finger measurements are deprecated and will be removed in future versions of Binah.ai's SDK.

A finger measurement is performed by covering the rear camera of a device with a finger.

Swift
do {
    let licenseDetails = LicenseDetails(licenseKey: "<ENTER_YOUR_LICENSE_KEY>")
    let session = try FingerSessionBuilder()
        .withImageListener(self)
        .withVitalSignsListener(self)
        .withSessionInfoListener(self)
        .build(licenseDetails: licenseDetails)
}
catch {
    let e = error as NSError
    print("Received Error. Domain: \(e.domain) Code: \(e.code)")
}
Objective-c
BNHLicenseDetails *licenseDetails = [[BNHLicenseDetails alloc] initWithLicenseKey:@"<ENTER_YOUR_LICENSE_KEY>"];
BNHFingerSessionBuilder *sessionBuilder = [[[[[BNHFingerSessionBuilder alloc] init]
                                             withImageListener:self]
                                            withVitalSignsListener:self]
                                           withSessionInfoListener:self];


NSError *error = nil;
id<BNHSession> _Nullable session = [sessionBuilder buildWithLicenseDetails:licenseDetails
                                                                     error:&error];
if (error != nil) {
    NSLog(@"Received Error. Domain: %@ Code: %ld", error.domain, (long)error.code);
}
